25 km south of Valence, in Drôme, lies the medieval city of Crest, the gateway to the Vercors Regional Nature Park. It has a historical curiosity that attracts many visitors: the highest keep in France, once part of a medieval castle. Standing on a rocky spur at a height of 52 metres, the Crest Tower was the major component of a fortress in the 12th century. Owned by several noble families over the centuries, including the Grimaldi family, princes of Monaco, it became a prison until the 19th century before being bought by the town of Crest and becoming a listed Historic Monument.

The impressively large Crest Tower is open to the public every day in the summer, for independent or guided tours. Don't miss the unobstructed view from the top, a stunning panorama of the Drôme Valley and the Vercors foothills!

Daredevils and thrill-seekers can try out an unusual activity: abseiling down the tower, supervised by qualified climbing instructors.
